As of January 1, 2017, Dr. Rothstein has limited his practice to providing Orthodontic Jaw Wiring for Weight-Control: OJW®: Weight-control. He provides this service in Brooklyn, NY and will soon announce a new office location in Portland,OR where the Oregon Board of Dentistry on June 23 created history by ruling that Dental Professionals are at liberty to Provide Weight-control services.

Analysis of Size and Position of the skull, Jaws and Dentition in the vertical and horizontal planes

Measuring and analyzing begins with by taking a lateral head X-ray of the patient’s skull and jaw:

Then creating a tracing of it and marking off the “natural” and “derived” landmarks typically used by orthodontists (EAM, Ar, S, Na, A, B, Gn, Pog, Gn, Me Go, Ar. etc. the most significant measuring points.

Here is shown a standard TEMPLATE showing a Normal 14 y/o F: In the female skull, growth is 97% complete by Skeletal age 14. + marks show one standard deviation of the landmark point (horizontally and vertically) in a sample N= close to 50 in all six samples.

The tracing is placed over the STANDARD (NORMAL) in a variety of ways to help the student (me) understand what the size and positional deviations are in the individual as represented in the tracing when compared with the standard.

Tracing of patient’s skull superimposed over the Normal Female Template. NOTE: How much the patient’s chin extends vertically down beyond the “Normal” Template chin.

This analysis can measure in angles and distances. But its main advantage is that you can visualize the deviation and report the divergences in “Standard deviations” (Visual-Dx ceph analysis.)

Assembling the positional and size facts.

Purchase price for the set of six standard templates is $300

Not every case requires having a lateral head x-ray (also called a “Cephalometric” X-ray). Any time such an X-ray is taken it is subject to some analysis whose size and angular norms were derived from samples of persons.

The uniqueness of the Normal Templates used in the Visual-Dx Ceph analysis is that the samples were composed of persons sub-grouped by “skeletal” age and gender”. This kind of study has no peer. These norms were used in my PhD dissertation to measure and visually allow me as an orthodontist to describe the true differences among adolescents and some adults who had “buck” (Class II, Division 1 malocclusion) compared to children who were “normal” (Class I).
